CEREC CAD/CAM – digital technology in the service of dentistry
This revolutionary technology enables the design and fabrication of dental prostheses with the help and accuracy of a computer. Result: aesthetic and accurate prosthesis in a very quick fabrication time.
Description du CAD/CAM
CAD-Computer Aided Design
CAM-Computer Aided Manufacturing
This technology have been in use for long in different fields, its use for dental purposes was worked out by a German enterprise called Dentsply Sirona (Siemens Group).
Fabrication process of dental prostheses
- Preparation of teeth
- Digital impression, scan (Digital impression taking with optical scanning by an infrared camera. The camera faithfully reproduces the form, the colour and the contact points of teeth as well.)
- CEREC design software (the design software conceives the prosthesis virtually and personalises it for each patient while creating a perfectly natural form and appearance)
- Fabrication with CNC milling machine (The data on the crown designed by the software will be sent to the milling machine which will sculpt the crown to an accuracy of a thousandth of a millimetre. Prostheses are fabricated with biocompatible materials that insure perfect appearance.)
- Crystallisation and glazing (The prosthesis gets its solidity and brightness in an oven designed for this purpose.)
Advantages
- The prosthesis can be fabricated within a few hours
- No need for impression taking
- No need for temporary crowns
- Beautiful appearance
- Accuracy
- Biocompatible material
Therapeutic indications
- Crowns, bridges
- Veneers
- Inlays, onlays
- Crowns on implant
